AFB1 — Zea mays

Summary

ZmAFB1 (ZM00001EB421340) on maize chromosome 10 encodes a protein with auxin receptor activity, auxin binding, NEDD8 transferase activity, and multiple transporter activities including auxin influx and efflux transmembrane transporter activity. The gene is associated with auxin signalling, SCF complex assembly, regulation of seed size, seed development, reproductive meristem phase change, and growth and developmental processes. It has been linked to numerous traits including seedling cotyledon size, adventitious root number, phototropism response, herbicide sensitivity, seed yield, biomass yield, root hair length, and flower development. The encoded protein localises to the nuclear SCF complex and ubiquitin ligase complex. Related genes in other species are linked to auxin response, root architecture, grain yield and size, leaf blast disease response, and herbicide resistance.
